Protect your young plants with the KGT cold frames 100 or 210. The mini greenhouses are made of transparent 6 mm ISO twin-wall sheets made of highly break-resistant polycarbonate and are UV-protected. Depending on the model, the cold frames have one or two practical, wide opening flaps that can be opened up to 90°. The manual opener allows the lid to be opened in various positions and also serves as a locking mechanism.
